Performance of Networked Control Systems

الملخص EN

Data packet dropout is a special kind of time delay problem.

In this paper, predictive controllers for networked control systems (NCSs) with dual-network are designed by model predictive control method.

The contributions are as follows.

(1) The predictive control problem of the dual-network is considered.

(2) The predictive performance of the dual-network is evaluated.

(3) Compared to the popular networked control systems, the optimal controller of the new NCSs with data packets dropout is designed, which can minimize infinite performance index at each sampling time and guarantee the closed-loop system stability.

Finally, the simulation results show the feasibility and effectiveness of the controllers designed.
